Brandon Myers came out of nowhere last season, when he more than doubled his production from his first three NFL seasons. It wasn’t just a fluke, though. He said there was a good reason for his sudden explosion.“I was given an opportunity to play last season,” Myers said. “The first three years there was always a guy ahead of me. That’s the way it is sometimes. Last year, I was given an opportunity to make some plays and I did that.”Now, after officially signing his one-year deal with the Giants on Sunday,The 27-year-old tight end plans to do so again.The Giants would be thrilled if the 6-3, 256-pound Myers even came close to duplicating his 79-catch, 806-yard, four-touchdown season for the Raiders. It not only would far exceed what they got out of the departed Martellus Bennett at that spot last season (55-626-6), it would be the most they’ve gotten out of a tight end since Jeremy Shockey’s rookie season in 2002 (74-894-2).The opportunity to do that is a big reason why Myers signed with the Giants. He led the AFC in catches by a tight end last season and had 27 more catches than any of his Oakland teammates. But the lack of interest he received on the free agent market showed him he still had something to prove to the NFL.
